Question by: Bonnie S on Sep 16, 2025, 1:25 PM

what's the difference between this TTC fitting and a regular hydraulic fitting

Answer by: Customer Support on Sep 18, 2025, 8:09 AM

TTC stands for Tube to Code connection, which means this fitting connects directly to hydraulic tubing without requiring a separate ferrule or sleeve. Regular hydraulic fittings often need additional components or specific tube preparation, but the TTC design simplifies installation by incorporating the sealing mechanism into the fitting body itself. The 4-wire spiral designation indicates it's built for high-pressure applications where you'd typically see four layers of wire reinforcement in the hydraulic hose.
